Avery Ng threw food at CY Leung to show how elderly people in the former colony are going hungry.

A popular pro-democracy activist in Hong Kong, Avery Ng, has thrown a sandwich at CY Leung, the Chief Executive of Hong Kong, as a form of protest against the Chinese government.

Ng, the leader of the Social Democratic Party in China, a pro-democracy group, was restrained by police as Leung dodged the sandwich.

In a video, Ng told the Strait Times, "I'm here to protest against CY Leung because of his introduction of the confirmation act which bar[s] certain candidates from running in this election. It undermines the legitimacy of today's election."

He went on to say, "I threw a sandwich to CY Leung just to remind him that, even, in Hong Kong there is a lot of elderly {people] who cannot – even – afford a simple breakfast".

Ng's protest came after Leung cast his vote for Hong Kong's Legislative Council Election (LegCo).

The Legislative Council is a committee, partially formed of democratically elected members, that has the power "to enact amend or repeal laws; examine and approve budgets" in the former British colony. Out of the 70 seats that are up for grabs in the LegCo election, 40 seats are voted by the public. China's central government selects representatives to fill the remaining 30 seats.

The Associated Press states that there is a 7.12% turnout - three hours after the polls opened. China has a population of 7.4 million and 3.8 million are expected to vote in the Legco elections.

The LegCo election is the last election of this year before the larger election for the chief executive election, which will decide the leader of Hong Kong, in 2017.
